Mine does this randomnly from time to time.
I've never "reprogrammed it", it just comes back at some point later. Switching the car off, locking it, leaving it 5 mins (the usual reboot for broken crap) seems to make no difference.
I'm sure the diagnostics has an error log, but I don't have VCDS to look and have never taken it to a dealer about it as it is just random.
